Wdrożenie zasad projektowania dziedzinowego (DDD) jest szansą na uzyskanie doskonałych wyników projektowania oprogramowania dla złożonych wymagań biznesowych. Aby podejście DDD ujawniło swoje zalety, konieczne jest zrozumienie potrzeb użytkowników i zidentyfikowanie właściwych problemów do rozwiązania. Dopiero potem można przystąpić do budowania modeli. Zaangażowanie zainteresowanych stron biznesowych w ten proces nie zawsze jednak przebiega efektywnie. Konieczne jest zrozumienie natury modeli dziedzinowych opartych na zachowaniu oraz tego, jaką rolę odgrywają one w budowie zwinnych i zmodularyzowanych systemów. Dzięki tej książce zrozumiesz praktyczne znaczenie złożoności dziedziny i behawioralnych aspektów języka dziedzinowego. Poznasz podstawowe zasady DDD i nauczysz się używać takich narzędzi jak EventStorming, Event Sourcing i CQRS. Dowiesz się, jak stosuje się DDD do różnych stylów architektonicznych, takich jak REST, systemy reaktywne i mikrousługi. Nauczysz się pracować we frameworku .NET Core 2.2, aby przetłumaczyć modele dziedzinowe na wykonywalny kod C#, oraz Vue.js, aby zbudować frontend aplikacji. Nie zabrakło tutaj również zagadnień refaktoryzacji kodu, numerowania wersji zdarzeń i migracji. W rezultacie poszczególne zespoły w organizacji będą mogły pracować elastyczniej i efektywniej dzięki ulepszonym usługom i oddzielonym interakcjom. W książce między innymi: angażowanie interesariuszy biznesowych do rozwiązywania złożoności dziedziny koncepcja kontekstu ograniczonego i agregatu projektowanie modeli tymczasowych na podstawie zachowania wzorzec CQRS i modele odczytu wykorzystujące rzutowania jednokierunkowy przepływ interfejsu użytkownika w Vue.js praktyczne stosowanie zasad projektowania dziedzinowego Programowanie dziedzinowe: tak się trafia w sedno potrzeb!

Gray Hat C#. Język C# w kontroli i łamaniu zabezpieczeń
Brandon Perry
C# to nowoczesny język programowania, który został od podstaw zaprojektowany jako obiektowy. Ta dojrzała technologia jest często wybierana przez twórców oprogramowania, również tego służącego do pokonywania zabezpieczeń systemów. Dzięki temu, że platforma .NET jest oprogramowaniem open source, w C# można pisać kod, który bez problemu będzie działał w każdym systemie operacyjnym. Co prawda język ten jest prosty i łatwy do nauczenia się, jednak dopiero gruntowna znajomość C# umożliwia efektywne tworzenie narzędzi związanych z bezpieczeństwem, służących choćby do wyszukiwania luk w infrastrukturze czy prowadzenia testów penetracyjnych. Ta książka jest przeznaczona dla specjalistów ds. bezpieczeństwa, którzy chcą korzystać z języka C# do takich zadań jak fuzzowanie, skanowanie w poszukiwaniu luk zabezpieczeń i analiza złośliwego oprogramowania. Opisano tu zarówno podstawy języka C#, jak i jego dość zaawansowane funkcje. Przedstawiono szereg bibliotek dostępnych dla tego języka. Pokazano, jak pisać kod wyszukujący luki w zabezpieczeniach i jak tworzyć eksploity. Przedstawiono sposoby korzystania z takich narzędzi jak Nessus, sqlmap i Cuckoo Sandbox. Dzięki technikom zaprezentowanym w książce administrator bezpieczeństwa bez problemu zautomatyzuje nawet najbardziej żmudne codzienne zadania! W tej książce między innymi: Podstawowe i zaawansowane funkcjonalności języka C# Generowanie kodu ładunków, również wieloplatformowych Skanery, w tym OpenVAS, Nessus i Nexpose Automatyczna identyfikacja luk umożliwiających wstrzyknięcie kodu SQL Tworzenie w C# narzędzi do inżynierii wstecznej C#. Sprawdź swój system zabezpieczeń! Brandon Perry jest programistą i gorącym zwolennikiem idei open source. Odkąd pojawiło się środowisko Mono, pisze aplikacje w języku C#. Tworzy też moduły dla frameworka Metasploit, analizuje pliki binarne i zarządza ciekawymi projektami (https://volatileminds.net/). Fascynuje się badaniami nad bezpieczeństwem systemów informatycznych. Chętnie dzieli się swoją wiedzą, pisze książki i pomaga innym w tworzeniu solidniejszego oprogramowania.
